Replicating the SRDF Protection Group Configuration to a Partner Cluster

After you have configured data replication, resource groups, and resources on your primary
and secondary clusters and you have created a protection group for those entities
on the primary cluster, you can replicate the configuration of the protection group
to the secondary cluster.

How to Replicate the SRDF Protection Group Configuration to a Partner Cluster

Before You Begin

Before you replicate the configuration of an SRDF protection group to a partner
cluster, ensure that the following conditions are met:

The protection group is defined on the remote cluster, not on the local cluster.

The device groups in the protection group on the remote cluster exist on the local cluster.

The system files on all nodes that can master the application have been updated for the application.

The application resource groups in the protection group on the remote cluster exist on the local cluster.

The Auto_start_on_new_cluster property of the application resource group is set to False. You can view this property by using the clresourcegroup command.

# clresourcegroup show -p auto_start_on_new_cluster apprg1

Setting the Auto_start_on_new_cluster property to False prevents the Oracle Solaris Cluster resource group manager from automatically starting the resource groups in the protection group. Therefore, after the Geographic Edition software restarts and communicates with the remote cluster to ensure that the remote cluster is running and that the remote cluster is the secondary cluster for that resource group. The Geographic Edition software does not automatically start the resource group on the primary cluster.

Application resource groups should be online only on primary cluster when the protection group is activated.

Set the Auto_start_on_new_cluster property to False as follows:

# clresourcegroup set -p Auto_start_on_new_cluster=False apprg1

The HAStoragePlus resource exists in the application resource group to enable devices and mount file systems.
